By reason of this provision of a plurality of cutting surfaces and the relative reversed arrangement of thesame, it is-impossible to. place a blade inpositioniupon chain so that a cutting edge will not be presented at the working end of the blade and in proper position to properly engage-the crop; It-will also be observed that each blade has four cut.- ting edges and it will, consequently, have a long life inasmuch as it is-possible to reverse the blade about its longitudinal axis and alsov about its-- transverse axis whereby to bring; a new cutting surface into working pos tion: when a usedsurface hasbecome too-- dull-to perform effective work At; one,end.of theframe is provided a sprocket wheel-15 which is mountedupon a pintle 16 fitted in a frame 17 which isjslidably-mountedu-ponthe; frame plate 1 and has a lower member restingonzsaid plate and an upper member overhang ng the sprocket, as;

A hood 42 is hinged at its rear edge upon the cap plates 21' and 29 to extend over and protect all' the working'parts, and: the usual 7 divider 43 may be employed. 1

It Will bereadilyseen from-the foregoing description, taken in connectionwith the accompanying drawings, that I. have provided an exceedingly simple cutting, apparatus:

which will operate continuously in one direction and in which the cutting blades will- 1 be necessarily fitted in the proper working position. Should any one blade be broken, it can be removed and a new blade substituted therefor in a very short periodof; time without any appreciable idleness of the machine.

Having thus described the invention, I

claim: 7 r

1. A cutting apparatus comprising an endthe several links of the chain, blades having longitudinal slots correspondingto said'l ugs and engageable thereover, and-means for retaming theblades on the lugs. 1

2, Cutting apparatus comprising an endless chain,- means for drivingthe chain, obliquely disposed lugs on the upper sides of the several links of the chain, guide lugs at the opposite sides of the first-mentioned lugs,

blades: provided centrally with slots correless chain,v means for driving thechain,iobliiquely disposed lugs on the upper sideof sponding to the first-mentioned lugs on the chain links and engageablethereover, the

blades fitting closely between the secondmentioned lugs, and means. for retaining the blades in engagement with the lugs.

3, A- cuttingapparatus comprising an-endless chain, means for driving the chainfobliquely disposed angular lugs'on the several links of thechain, guide lugs disposed onthe links of the chain at opposite sides ofsaid angular lugs, blades engageable over :the' angularlugs and between the guide lugs,and holding, elements 7 mounted on the first-mentionedlugs andrad'apted inoneposition to project be yondrthe same over the respective blades.

3 l 4.- In a, cutting apparatus, -a-.relativelylong flat blade having cutting; portions upon: its

opposite side-edges, there being-twocutting V portionstupon each side edge and'the cutting port onsupon-the'sameuedge and at-the same ends-of the opposite edges; being; oppositely beveled, p

' "5. In a cutting apparatus, a an' endless chain, blades carried by the several links of" V the chain, a sprocket engaged with said links to actuate the same and provided with ratchet recesses in its upper side," a drivin'g member 1 1 I disposed above and coaxially with; said sprocket, and a dog mounted on theunder side of the driving member and adapted to engage the ratchet'recesses" in the driven H sprocket. 1 I C Intestimony whereof I aflix my signature.
